Alternative bottom drop and straight tee discharge from bulk tank having various extensions for automatic and manual operations of the tee valve

An alternative bottom drop or straight tee discharged from a bulk tank trailer vehicle having various extensions for automatic and manual operations of the tee valve:

• a hopper tee, said hopper tee having a horizontal section through which pressurized air and granular material may flow, and an integral vertical section through which the bulk material flows upon discharge from the tank trailer;
• said tee having a pair of seats, one formed at the bottom of the tee beneath its vertical section, and the second seat being provided approximately perpendicularly with respect to the first seat, and structured at the incoming flow portion of the horizontal section of the tee at its incoming air flow location beneath the vertical section of said tee;
• a disc-like valve, said disc-like valve having a valve means for locating and seating proximate either of said seats provided within the tee, said disc-like valve having a circular disc portion, and upstanding integral supports;
• a pair of bearings shafts, mounted to either side of the horizontal section of the tee, said bearing shafts mounting the upright supports of the disc-like valve for pivotal movement, provided for either a lowering of the disc-like valve to the bottom of the tee, or pivoting of the disc-like valve approximately 90° for blocking the incoming flow of pressurized air through the horizontal section of said tee;
• and
• mechanical means for providing either the automatic or manual turning of the disc-like valve to attain either a bottom drop unloading of granular material from the tank trailer, or to provide for the horizontal flow of granular material through the tee from said tank trailer vehicle.
